Specification Overview
The BMI0702T26A is a single-phase servo motor in the BMi series, rated 700 W at 230 V input and 400 W at 115 V input, with a nominal speed of 4000 rpm at 230 V. The IP65-rated enclosure and integrated EMC filter make it suited for controlled environments where particle ingress and conducted emissions must be managed. Natural convection cooling — no fan — eliminates a source of particulate shedding and moving parts. The absolute single-turn SinCos Hiperface encoder returns position on power-up without a homing sequence, reducing mechanical wear and cycle time in precision axes. Stator resistance is 2.7 Ω at 20 °C, inductance 7.8 mH, and the torque constant is 0.63 N·m/A. Continuous stall torque is 2.48 N·m across the 115…230 V range, and peak stall torque reaches 6.6 N·m. The motor flange is 70 mm with a 60 mm centring collar and 11 mm untapped shaft. Feedback and power are terminated through a printed circuit board connector, keeping the cable interface compact. Maximum radial force is 710 N at 1000 rpm, derating to 390 N at 6000 rpm. Axial force limit is 0.2 × Fr. Shaft length is 23 mm. The motor is cooled by natural convection only, so no external air supply or fan is required — a feature that aligns with low-participation areas in semiconductor fabs.
